WordPress 6.3 RC3 is ready for download and testing.
This version of the WordPress software is under development. Please do not install, run, or test this version on production or mission-critical websites. Instead, you should evaluate RC3 on a test server and site.
The WordPress 6.3 release is scheduled for August 8, 2023—just one week away. Now is your last opportunity to test it before the general release.
For a deeper look into this release, read this overview of the 6.3 release cycle, check the Make WordPress Core blog for 6.3-related posts, review new features in WordPress 6.3, or watch a recorded demo.
What’s new since RC2
Since the RC2 release on July 25, 2023, there have been approximately 14 issues resolved in Github and Trac. To prepare for 6.3 general availability, RC3 also addresses several bugs and adds fixes for retrieving templates (#4940) and resolving child theme issues (#53138). Thank you for testing, WordPressers!
Developers and extenders should review the comprehensive WordPress 6.3 Field Guide for detailed technical notes regarding new features and improvements.

Keep WordPress bug-free—help with testing
Testing for issues is a critical part of developing any software, and it’s a meaningful way for anyone to contribute—whether you have experience or not. While testing the upgrade process is essential, trying out new features is too.
- Encountered an issue? Please report it to the Alpha/Beta area in the support forums. If you are comfortable writing a reproducible bug report, you can file one on WordPress Trac. You can also check your issue against a list of known bugs.
- New to testing? This detailed guide is a great place to start if you’ve never tested a beta/RC release.
- Want to know more about testing releases in general? Follow along with the testing initiatives in Make Core and join the #core-test channel in Making WordPress Slack.
Search for vulnerabilities
The monetary reward for reporting new, unreleased security vulnerabilities is doubled between the Beta 1 release and the final release candidate (RC). Please follow responsible disclosure practices as detailed in the project’s security practices and policies outlined on the HackerOne page and in the security white paper.
Update your theme or plugin
Do you build themes or plugins? Your products play an integral role in extending the functionality and value of WordPress for users of all types worldwide.
This is your final opportunity to test your latest versions against RC3. You will want to continue your testing and update the “Tested up to” version in your plugin’s readme file to 6.3.
